Run the OneDrive Troubleshooter for Windows 8.1

Some of the most common problems you might experience using OneDrive are caused by a few issues. Run the OneDrive Troubleshooter app to find and automatically fix these common issues, which might resolve the problems you're experiencing.

Send diagnostic information to Microsoft. Selecting this tells the Troubleshooter to gather technical information about any problems it may have found. It saves a log file to your desktop, in case you need to provide it later to Microsoft support.

Reset OneDrive. Selecting this button fixes most issues with OneDrive. It resyncs all of your files, which might take a while if you have a lot of files. Resetting OneDrive doesn't change any OneDrive settings you've already made.
